METHOD OF AND APPLIANCE FOR, REfLlEVl NG TRUCK-S.

SPECIFICATION forming part of Letters Patent No. 359,323, dated October 51886.

I Application filed J misfit), 1885. Serial No. 170,094. (No model.)

New York, have invented a certain new and useful Method of Relieving Trucks and Appliances to be Employed therein,- and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others to make and use the same, referenceibeinghad to the accompanying drawings, which form part of this specification.

My invention has for itsobject a method of relieving broken-down trucks and other vehicles, and also certain appliances to be used for that purpose, whereby, without unloading the vehicle, the broken parts may be quickly and conveniently supplemented with suitable devices, by means of which the vehicle may be used to complete its delivery route or driven to its destination without straining or otherwise injuring the same or its parts.

In carrying out my invention I use the devices shown in the drawings, in which Figure 1 is an elevation of a double Wheel, with por-I tions broken away to show the parts. Fig. 2 is a section of the sameon the line we of Fig. 1. Fig. 3 is an elevation of the inner wheel, shown from the side opposite to that shown'in' Fig. 1. Fig. 4 is an elevation of the axle-box H. Fig. 5 is an elevation of the axle-box .plate G. Fig. 6 is an elevation of one form of axle with an adjustable spindle, showing the spindle set in one position. Fig. 7 is an elevation of a form of axle with parts for rigid adjustment to the inner wheel, D. Fig. 8 is an end view of the axle Fig. 7. Fig.9 is a plan of the axle Fig. 7. Fig. 10 is an elevation of another form of axle with an adjustable spindle; Fig. 11 is a sectionthrough the line y y of Fig. 10. Fig. 12 is an elevation of the axle shown in Fig. 6, showing the spindle set in another position. Fig. 13 is an elevation of the rear of a truck with abroken axle," showing the wheel Fig.1 and the axle Fig. 7 applied. Fig. 14 is an elevation of the rear of a truck-axle, the spindle broken off, show-. ing the wheel Fig. 1 and the axle'Fig. 12 applied.

Similar letters of reference indicate like parts in all the drawings.

A part of my invention consists of a novel wheel, Fig. 1, which is essentially two wheels arranged so that one shall operatewithin' the other.

The outer wheel consists of a tread, A, and collar B, suitably connected by spokes (3, so as to form a solid structure, as shown in Figs.

'1 and 2. Within the collar B an inner wheel, ID, is arranged, so that it may revolve easily therein, and I prefer to employ friction-rollers a a for that purpose. A convenient recepa a pivoted therein. This'frame, with therollers, is inserted next to the collar B,and within the central opening is placed the inner wheel, D, the several parts being of such rel- ;ative size that they fit snugly together and 1 move easily within each other.

The parts are then secured together, which is conveniently done by the annular bands E E, bolted together through the collar B. V

The inner wheel consists, essentially, of the rim D, having secured Within .it vertical bars .F F, between which the axle-box H is to be adjusted. A convenient Way to construct these parts is to cast the rim D with flanges D D, all in one part, and then bolt the bars F F to such flanges D D, as indicated'in Figs. 2 and 3; but the bars F F may be secured'to the rim D iuany other convenient manner.

In the open space between the bars F F the axle-box H is to besecured. This consists of a central portion, H, having lateral projections H, provided with suitable holes to receive the bolts 0 c. The portion H is of suitable size to fit snugly between the bars F F, and'projects far enough to fit into the plate G, which also has holes to receive the bolts 0 c, and the bars F F are likewise provided at suitable intervals with corresponding holes for the same bolts 0 c. When the axle-box H has b een i'nserted between the bars F F, with the spindlehole on the plane desired, the plate G is' fitted thereon, and all the parts are securely fastened in position bythe bolts passing through the plate G, bars F F, and parts H, as is clearly shown in the drawings. It will thus beseen that by the use of this wheel the spindle of the tacle'for the friction-rollers is formed of two annular parts,b b--one on each side of the j wheelrivetedtogether at suitable intervals to :form a frame, and having the friction-rollers axle can be supported to operate on any plane by the adjustment of the box H,when it is convenient or desirable to havethe axle-box H revolve around the spindle; but of course it will be apparent, also, that, if desired, the inner wheel, D, may be rigidly attached to an axle, and it will itself act as an enlarged spindle.

To attach this wheel to avehicle, I may employ auxiliary axles, and I show several forms of such devices. In Fig. 6 is shown an axle arranged so that the spindle may be adjusted upon a plane varying in relation to the axletree. I is an axle-tree terminatingin a ratchetarm, I. On a corresponding ratchet-arm, J, is secured the spindle K, and the two ratchetarms I and .I are held together by the clamps or clips (I d, one or both of which may be pivoted or bolted, the one to the arm I and the other to the arm J, as shown in Figs. 6 and 12. When it is desired to adjust the spindle K, it is only necessary to unscrew the clips 01 d sufficiently to withdraw the ratchet-teeth from each other, move the spindle to the position desired, then u re-engage the ratchet-teeth in that position and screw up the clips. In this form of device the spindle may be shifted to a distance corresponding to the thickness of the ratchetteeth. In some instances I may use the arrangement for adjusting the spindle shown in Figs. 10 and 11. In that device, 0 is an axle-tree terminating in the arm P, which carries a threaded red, It, provided with a square top, U, so as to be conveniently turned by a wrench. On this rod R is mounted the spindle S, projecting from the spindle-carrier T, which is recessed to move up and down on the arm P, as clearly shown in Fig. 11. The spindle-carrier T is threaded corresponding to the rod R, and is operated by the rod R, which turns within it as a screw, raising or lowering the spindle as the nut U is turned. The parts may be strengthened and rigidly held in place by means of the clamps or clips formed of the rods ll, plate m, and nuts a, by means of which thespindle-carrier T may be drawn tightly to the arm 1?. These two devices (shown in Figs. 6, 12 and 10,11) are especially applicable when the spindle is broken off the axle and it is desired to use a spindle for a wheel in relieving a vehicle, as spindles may be provided for them in sets to lit wheels with axleboxes of various sizes. I may also employ with my wheel Fig. 1 an auxiliary axle not having any spindle, but terminating in a square part or support, such as is shown in Figs. 7 to 9. In this, L is an axlet ee having a shoulder, N, which may correspend in size to the part H of the axle-box shown in Fig. 4, the side projections having corresponding holes for bolts. Outward from the shoulder N projects a square portion, M, of suitable size to fit between the bars F F, where it is to be secured rigidly in position, its outer end resting in a suitable slot in the plate f, the plate f and shoulders N being secured together by means of the boltst' 'i,passing through the holes in the bars F F, the part M resting between such bars corresponding to the attachment of the spindle-carrier or axlebox H.

I show two instances of applying my invention. In one, Fig. 13, where the axle-tree j is broken, and the wheel may be broken also, the

axle-tree L is shown attached. to the broken 7 5 axle by means of the clips or clamps k k, a wooden block, g, being employed to brace the parts where necessary, and my double wheel is attached, the spindle on the axlej passing between the bars F F, and the square part M13 secured between the bars F F, as above described. In this case the inner wheel, D, is rigidly attached to the axles j L, and the outer wheel turns around it.

In Fig. 14. the spindle of the axlep is shown broken off, and my axle I is shown secured to the axle p by the clips or clamps k k, and the parts likewise braced by wooden blocks 9 y, where deemed necessary.

H, my double wheel being employed; but it will be seen that if the wheel of the vehicle is not itself broken, and a spindle, K, of suitable size is on hand to fit such wheel, my double wheel would not necessarily be required in this instance, but the truck might be taken home on its own wheel. by the use of the axle with spindle capable of being adjusted at the height required.

While I show and describe only two instances of employing my invention, I do not limit myself thereto, as my devices are intended to be applied in any case where either the axle or the wheel, or both, are rendered useless, and

both or either of my devices may be employed 05 either on the front or rear of a vehicle, the auxiliary axles being placed either above or below the axle of the vehicle, as circumstances may require; and I believe that these devices will be found sufficient to safely carry a vehicle in every instance of breakdown of the runninggear.

It will be seen that by the use of my invention the broken parts of the running-gear can be quickly and easily supplemented by devices I r 5 that will take the place of the broken parts and hold and carry the body of the vehicle upon its proper plane and in substantially the same manner as by the broken parts, so that there will be no straining or injury to the 0 structure, as frequently happens when the body is supported upon a beam or pole after a wheel or axle is broken. By my invention, also, a vehicle may be quickly fitted to complete the delivery-route upon which it may be 12 5 employed, so that the loss of time and annoyance of having to send for or hire another vehicle, unload the broken one and reload its freight, and then send the broken vehicle home, thereby incurring the expense of two vehicles and two drivers, are all avoided.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In the drawings, the spindle K is shown inserted in the axle-box 9o 1. The device shown for relieving disabled vehicles,consisting of an axle-tree terminating in a suitable adjusting device, and an independent spindle adapted to be supported thereby, in combination with asuitable reliefwheel, as Fig. 1, substantially as described.

2. An axle-tree terminating in a suitable adjusting device, in combination with an independent spindle adapted to be supported by such device on varying planes relative to such axle-tree, substantially as described.

3. An auxiliary axle consisting of the axletree I, having ratchet-bar I, ratchet-bar J carrying the spindle K, and a suitable device adapted to adjust the same and hold them in position, substantially as described.

4. A relief-wheel consisting of atread with suitable inner bearings, and an inner wheel adapted to operate in such bearings, such inner wheel provided .with suitable supports, F F, in 20 with supports F F, adapted to receive the 25 ends of several independent axle-trees, sub stantially as described and shown.
